Conclusion: Relative to WW, patients randomized to PT reported similar PROMs but incurred significantly higher direct costs (10.0x) and imposed a greater economic burden on the healthcare system (3.4-6.0x). Accordingly, WW resulted in significantly higher (5.9x) patient value than PT. Although additional high-level, multicenter studies are needed to corroborate these findings, the present study may support physicians and patients in pursuing the most appropriate treatment plan for each patient based on their individualized needs and preferences.

Conclusion: There are significant nationwide disparities in the likelihood of receiving operative management for rotator cuff tear patients of differing race/ethnicity, payer status, and socioeconomic status. Further investigation is needed to fully understand and address causes of these discrepancies to optimize care pathways.

Accelerated Versus Standard Physical Therapy in Patients with Transtendinous Rotator Cuff Repair: A Propensity-Matched Cohort Study, J Shoulder Elbow Surg

Conclusion: Accelerated PT following transtendinous RCR is associated with significant improvement in AROM at 6 weeks and 3 months postoperatively. Further, the early motion may help obviate the development of severe postoperative stiffness without any evidence of higher rotator cuff retear rates.

Worsening Racial Disparities in Patients Undergoing Anatomic and Reverse Total Shoulder Arthroplasty in the United States, J Shoulder Elbow Surg

Conclusion: Racial disparities in patients undergoing TSA and RTSA are worsening over time. Black patients undergo TSA and RTSA at lower rates than white patients regardless of insurance status and have increased odds of complications and mortality. Improved initiatives are needed to reduce these racial disparities and further research is warranted to understand their root causes.

The new dynamic isotonic manipulation examination (DIME) is a highly sensitive secondary screening tool for supraspinatus full-thickness tears, J Shoulder Elbow Surg

Abraham PF, Nazal MR, Varady N, Gillinov SM, Quinlan NJ, Alpaugh K, Martin SD. The new dynamic isotonic manipulation examination (DIME) is a highly sensitive secondary screening tool for supraspinatus full-thickness tears. [published online ahead of print, 2020 Jul 7]. J Shoulder Elbow Surg. 2020 Nov 1; 29(11): 2213-2220. doi:10.1016/j.jse.2020.06.029 PMID: 32650076

Conclusion: DIME is highly sensitive for supraspinatus FTTs in patients with negative traditional rotator cuff PE tests for whom there is still high clinical suspicion of FTTs. Thus, this test is an excellent secondary screening tool for supraspinatus FTTs in patients for whom clinicians suspect rotator cuff pathology despite negative traditional static PE tests. Given its high sensitivity, a negative DIME test rules out supraspinatus FTT well in these patients, and can therefore better inform clinicians which patients should undergo MRI. In addition, the angle at which patients first report pain on unopposed active shoulder abduction is highly specific for supraspinatus pathology.

A value-based care analysis of magnetic resonance imaging in patients with suspected rotator cuff tendinopathy and the implicated role of conservative management, J Shoulder Elbow Surg

Cortes A., Quinlan, NJ, Nazal, MR, Upadhyaya, S, Alpaugh, K, Martin, SD. A value-based care analysis of magnetic resonance imaging in patients with suspected rotator cuff tendinopathy and the implicated role of conservative management. J Shoulder Elbow Surg. 2019 Nov;28(11):2153-2160. doi: 10.1016/j.jse.2019.04.003. Epub 2019 Jul 4.

Conclusions: The use of MRI before a trial of conservative management in patients with atraumatic shoulder pain, minimal to no strength deficits on physical examination, and suspected cuff tendinopathy other than full-thickness tears provides negative value in the management of these patients, at both the individual and population level.
